Portable biometric monitoring devices having location sensors

摘要

Assisted-GPS for a portable biometric monitoring device is provided. The portable biometric monitoring device may obtain updated ephemeris data from an associated secondary device via a short-range, low-power communication protocol. The secondary device may be a computing device such as a smartphone, tablet, or laptop. Various rules may control when the ephemeris data is updated. The ephemeris data may be used in the calculation of the global position of the portable biometric monitoring device. Additionally, the portable biometric monitoring device may communicate downloaded position fixing data to the associated secondary device. The associated secondary device may then calculate the global position from the position fixing data.

主权项

1. A method of determining a global position of a worn biometric monitoring device, the method comprising:
(a) periodically and automatically syncing the worn biometric monitoring device with a secondary device associated with the worn biometric monitoring device, wherein the periodic and automatic syncing comprises providing the worn biometric monitoring device, for a plurality of instances, with current ephemeris data from the secondary device using a wireless short-range, low-power communication protocol according to a schedule, (b) determining that a global position of the wearable biometric monitoring device should be calculated, (c) calculating the global position using the current ephemeris data obtained in (a), wherein at least some of the syncing is conducted when the wearable biometric monitoring device is not determining the global position of the wearable biometric monitoring device and (d) determining a timeframe of the current ephemeris data provided to the worn biometric monitoring device during the syncing by monitoring a pattern of interaction of a user with the biometric monitoring device.
